Objective: The determination of the cellular lineage in acute leukemia is a crucial step in the diagnosis and the later therapeutic conduct. In Tunisia, emerging country, some cases of acute leukemias are still treated on the basis of an only cytologic study because of lack of cytometry. Our objective is to realize a confrontation between cytology and flow cytometry in the diagnosis of AL and to analyze discrepancies.
Patients And Methods: The study concerns 100 cases of AL. A second double-blind examination of the bone marrow smears of acute leukemias is realized by two cytologists and confronted to immunophenotyping.
Results: In two cases of AML, flow cytometry reassigned lineage into T ALL and biphenotypic AL. In three cases of ALL the lineage was reassigned into undifferentiated acute leukemia (2 cases) and biphenotypic acute leukemia (1 case). Lineage was not established in four cases, immunophenotyping allowed the diagnosis of B ALL in 3 cases, and of biphenotypic acute leukemia in 1 case. In both cases of discrepant findings, flow cytometry allowed the diagnosis of biphenotypic acute leukemia in a case and of AML in the other one.
Conclusion: The cytological study remains insufficient in the diagnosis of lineage even with experimented cytologists. Immunophenotyping is essential in lineage assignment and reassignment.

In addition to biological factors, maternal exposures during pregnancy can contribute to leukemogenesis in offspring. We conducted a population-based cohort study in Sweden to investigate the association between risk of acute lymphoblastic leukemia (ALL) in offspring and maternal anthropometrics during pregnancy. A total of 2,961,435 live-born singletons during 1983-2018 were followed from birth to ALL diagnosis, end of age 18, or end of 2018.

This report describes a rare case of anuric acute kidney injury related to suspected urate nephropathy in a 23-year-old male with chronic phase of Chronic Myeloid Leukemia (CML). The patient presented with anuria and limb edema, with a history of imatinib-treated CML. Investigations revealed probable urate crystals causing bilateral hydronephrosis and hydroureters.

Acute myeloid leukemia (AML) is a complex cancer, yet advances in recent years from integrated genomics methods have helped improve diagnosis, treatment, and means of patient stratification. A recent example of a powerful, multimodal method is DOGMA-seq, which can measure chromatin accessibility, gene expression, and cell-surface protein levels from the same individual cell simultaneously. Previous bimodal single-cell techniques, such as CITE-seq (Cellular indexing of transcriptomes and epitopes), have only permitted the transcriptome and cell-surface protein expression measurement.

Acute myeloid leukemia (AML) is the most common acute leukemia and is predominantly affecting older patients. It is a heterogenous disease, showing a broad spectrum of genomic alterations and mutations that influence the clinical outcome and treatment options. The expression of the signal transducer and activator of transcription 3 (STAT3) is often dysregulated in AML and its constitutive activation is associated with poor outcome.

Background: Acute myeloid leukemia (AML) is still a threaten to human health due to its high occurrence and poor prognosis. Mesenchymal stem cells (MSCs) in bone marrow microenvironment (BMM) play a critical role in the development of AML. This study elucidated the interaction between MSCs and AML cells and its underlying mechanism.
